How do I know if I have air suspension?
Air suspension is a type of vehicle suspension system that uses air springs instead of traditional metal coil springs. If you're unsure whether your vehicle has air suspension, there are a few key signs to look for. In this article, we'll provide a detailed overview of how to identify if your vehicle is equipped with an air suspension system.
What is Air Suspension?
Air suspension systems use pressurized air, rather than metal springs, to support the weight of a vehicle and provide a smooth, comfortable ride. The air springs are connected to an air compressor that maintains the appropriate air pressure in the system. This allows the suspension to automatically adjust to changes in load, road conditions, and driving dynamics. Air suspension is commonly found in luxury vehicles, trucks, and SUVs, as it provides a more refined and customizable ride compared to traditional coil spring suspensions.
Signs Your Vehicle Has Air Suspension
Here are the main indicators that your vehicle is equipped with an air suspension system:
- Adjustable Ride Height: One of the key features of air suspension is the ability to raise or lower the vehicle's ride height at the push of a button. This allows the driver to optimize the suspension for different driving conditions, such as increasing ground clearance for off-road use or lowering the vehicle for improved aerodynamics on the highway.
- Smooth, Floating Ride: Air suspension provides a very smooth, cushioned ride quality, as the air springs absorb bumps and vibrations more effectively than traditional metal springs. The vehicle will feel like it's "floating" over the road.
- Compressor Noise: You may hear the air compressor running periodically to maintain the proper air pressure in the suspension system. This is a telltale sign of an air suspension setup.
- Suspension Sensors: Air suspension systems use various sensors to monitor the air pressure and ride height, which can be displayed on the vehicle's dashboard or infotainment system.
If your vehicle exhibits these characteristics, it's highly likely that it's equipped with an air suspension system. However, the only way to be certain is to consult your owner's manual or have a professional mechanic inspect the suspension components.
Advantages of Air Suspension
Air suspension offers several key benefits compared to traditional coil spring suspensions:
- Improved Ride Quality: The air springs provide a smoother, more comfortable ride by absorbing bumps and vibrations more effectively.
- Adjustable Ride Height: The ability to raise or lower the vehicle's ride height allows for better handling, improved aerodynamics, and increased ground clearance when needed.
- Load-Leveling Capabilities: Air suspension can automatically adjust the ride height to maintain a level vehicle stance, even when carrying heavy loads or towing a trailer.
- Enhanced Stability and Handling: The precise control over the suspension provided by air springs can improve the vehicle's stability and handling, especially during cornering and high-speed maneuvers.
While air suspension systems are generally more complex and expensive than traditional coil spring setups, the improved ride quality, adjustability, and performance benefits make them a popular choice for many luxury and high-end vehicles.
How can I tell if my car has air suspension?
Just kneel down a bit and look in the wheel well, front or back. Air suspension should have a bag like shape with the shock absorber sticking out bottom, for non-airide would be shock and spring.
How do you diagnose air suspension?
To identify the source of an air leak, it's best to have a professional mechanic put the air suspension system through a series of tests. They will use specialised tools to pressurise the system and then spray soapy water along all air lines and connections to check for escaping air bubbles.
